5
You look for the largest perfect square, and take it out. In this case: root(125) = root(25 x 5) = root(25) x root(5) = 5 x root(5).
The idea is to take out perfect squares. Root(50) = root(2 x 25) = root(2) x root(25) = 5 x root(2).
The number of which the square root is to be found is called the "radicand." The symbol before the number is called the radical sign. ( √ ) E.g. √4 = 2, √25 = 5
The square root of 25 is 5.
2i radical 5 * * * * * No. it is ± i*radical(25) which is ± 5i. Not sure why the answer is requireed in radical form.
25 times the square root of 2
5
5
square root of 125= 25 times 5 under the radical (25 has a square root so you can take that out of the radical)= 5 times the square root of 5 (Thats your final answer with no calculator)
If by "radical" you mean "square root of", then yes. Both square roots of 25 are real numbers.
You look for the largest perfect square, and take it out. In this case: root(125) = root(25 x 5) = root(25) x root(5) = 5 x root(5).
50 = 2*25 so sqrt(50) = 5*sqrt(2)
sqrt 175 = sqrt 25 x sqrt 7 = 5 x sqrt 7
